5). Demag compensation
Demag compensation is a feature to protect from motor stalls caused by long winding
demagnetization time after commutation. The typical symptom is motor stop or stutter upon
quick throttle increase, particularly when running at a low rpm. As mentioned above, setting high
commutation timing normally helps, but at the cost of efficiency.
Demag compensation is an alternative way of combating the issue. First of all, it detects when a
demag situation occurs.
- In this situation, there is no info on motor timing, and commutation proceeds blindly
with a predicted timing.
- In addition to this, motor power is cut off some time before the next commutation.
A metric is calculated that indicates how severe the demag situation is. The more severe the
situation, the more power is cut off.
When demag compensation is set to off, power is never cut.
When setting it to low or high, power is cut. For a high setting, power is cut more aggressively.
Generally, a higher value of the compensation parameter gives better protection.
If demag compensation is set too high, maximum power can be somewhat reduced.
6). Motor timing
Commutation timing can be set to low/mediumlow/medium/mediumhigh/high, that
correspond to 00/7.50/150/22.50/300 timing advance.
Typically a medium setting will work fine, but if the motor stutters it can be beneficial to
change timing. Some motors with high inductance can have a very long commutation
demagnetization time. This can result in motor stop or stutter upon quick throttle increase,
particularly when running at a low rpm. Setting timing to high will allow more time for
demagnetization, and often helps.
7).Brake on stop:
Brake on stop can be enabled or disabled. When enabled, brake will be applied when throttle is
zero. For nonzero throttle, this setting has no effect.
8). Others
-Beep strength:
Sets the strength of beeps under normal operation.
-Beacon strength:
Sets the strength of beeps when beeping beacon beeps. The ESC will start beeping beacon beeps
if the throttle signal has been zero for a given time. Note that setting a high beacon strength can
cause hot motors or ESCs!
-Beacon delay:
Beacon delay sets the delay before beacon beeping starts.
-Programming by TX:
If disabled, throttle calibration is disabled.
-LED control:
LEDs can be controlled on ESCs that support it. Up to 4 LEDs can be turned on or off.
